The quote accurately reflects what Ruse believes. Your protest is just a reflection of your embarrassment at his honesty. LOL
However, the claim is sometimes, and more plausibly, made that evolutionary theory, along with some other scientific theories, functions as a kind of attitudinal metaphysical system [Ruse 1989]. It is (in my opinion, rightly) thought to influence the kinds of problems and solutions dealt with by science. There is no problem with this, since in order for a discipline to make any progress, the field of possible problems (essentially infinite, to use a malapropism) must be restricted to some set of plausible and viable research options. The theory of evolution as now consensually held acts to narrow the range and limit the duplication required. This is harmless, and is true of any field of science.
Ruse also describes what he calls "metaphysical Darwinism" [Ruse 1992] (as opposed to "scientific Darwinism") which is indeed a metaphysical system akin to a worldview, and which has expressed itself in numerous extra-scientific philosophies, including Spencer's, Teilhard's, and Haeckel's, or even the quasi-mystical views of Julian Huxley. These must be considered separate to the scientific theory, and are often in contradiction to the actual scientific models.
Other than this, the "metaphysic" of evolution by selection is primarily a research-guiding mindset that has been extraordinarily fruitful where no others have been [Hull 1989]. However, as a metaphysic, evolutionary theory is fairly poverty-stricken. This is what should be true of a scientific theory; for the number of conclusions beyond the empirical evidence that can be conjectured is unlimited. Any theory that committed itself to a metaphysical conclusion as a logical inference would be almost certainly false.
Those who need Cosmic Meaning need not fear that any version of evolutionary theory prohibits it; although neither does nor can it support it. Those evolutionists who have either argued in favour of Cosmic Meaning on the basis of evolutionary theory, or have argued that there can be no Cosmic Meaning because things evolve, are both wrong. The conclusions do not follow from the premises, simply because 'is' does not imply 'ought'. John Wilkins
John Wilkins, the author of the above quote, is a Philosopher of Science who has actually read and understood Ruse.
I suspect you have not.
